HOO'F-TRIMMING TOOL.

SPECIFICATION forming part of Letters Patent No. 350,340, dated October5, 1886.

Almlication filed February 16, 1886. Serial A a-192,064. (X model.) I

by declare the following to be a description of the same, and of themanner of constructing 4 and using the invention, insuch full, clear,

concise, and exact terms as to enable any penson skilled in the art towhich itappertains to construct and use the same, reference being had tothe accompanying drawings, forminga part of the specification, theprinciple of the invention being herein explained and the best mode inwhich I have contemplated applying that principle, so as to distinguishit from other inventions.

My invention has for its object to provide an improved tool for theconvenientand accurate paring or trimming of the hoofs of horses in theprocess of shoeing. The main featuresare the peculiar construction andrelative adjustment to each other of the opposite jaws of said tool,adinissibly called nippers, and the trimming or cutting means with whichsaid jaws are provided,as are more fullyand'plainly shown in thedescription that follows.

In the drawings, Figure l is a front end view of the tool. Fig. ,2 is aside elevation of tool,witl1 certain parts in section. Fig. 3 is adetail perspective view of one end of jaw D and its shear-blade detachedtherefrom. Fig. 4 is a detail perspective of end of jaw B, and havingits knife detached therefrom. Fig. 5 is a detail perspective of a knifewhich fits in jawB. Fig. 6 is a detail perspective view of anvil-blockwhich fits in jaw D. Fig. 7 is a detail crosssection of jaw D, taken ondotted line,as indicated. Fig. 8 is a detail cross-section ofjaw D,takenon dotted line, as indicated.

Arepresents one of the arms of the tool, terminating in the jaw B. C isthe other arm of the tool, terminating in the jaw l). E is the pivot bywhich said arms are connected together. Said jaws bend toward each otherin very nearly the same horizontal plane.

Jaw B is provided with the knife F, which projects suitably forward ofthe inner end of said jaw. Said jaw has on itsouter terminal surface therecess a, within which shank b of knife slides. Set-screw 0, passingthrough 1ongitudinal slot 0 of shank Z), holds said knife at anyadjusted position in said recess. At a centrally rear point of recess ais formed the longitudinal lug d, through which works screwe, adapted tohave bearing against the shank of knife F, whose object is to push saidknife forward in said recess, as may be necessary for the taking up ofwear on the cutting-edge of said knife.

The terminal bent portion f of jaw D lies in a' horizontal planesomewhat outwardly beyond the horizontal plane of knife F, and of thecorresponding plane ofjaw B, in which the shank of said knife isinserted, so that said knife may work substantially under the innerhorizontal surface of said jaw D. Said terminal bent portionf o'fjaw Dmay be outwardly somewhat convex, the better to fit the naturalcurvature of the hoof of the horse, and the extreme end 9 of said jaw Dis concave, and also beveled inwardly, forming shear-block h. Directlyunder said block is located shear-blade i, having its front edgeconcave,corr.esponding substantially with the concavity of block h. Saidblade t is removable, and also adjustable toward and from said block itby means of screws 9', having collars 111, one screw on each side of jawD, or by any other equivalent means. Said screws 7 are so connected withblade 2' that by screwing them one way said blade is started somewhataway from block h, and by screwing them in the opposite direction saidblade is drawn closerto said block.

Immediately in rear of shear blade 2' is formed, on the under face ofterminal portion f of jaw D, the dovetail crossslot k, into which isfitted the anvil-block G, which forms the terminus of the cutting strokeof knife F. Said anvil-block has its inner lateral edges beveled tofitin said slot is, and when worn is easily removable from said slot forthe purpose of its being turned or replaced or otherwise.

Knife F is substantially straight across its cutting-edge, while thereciprocating face of block 71. and .front edge of blade 2' are concave,which several forms of said parts in co-operation cause the outercorners of knife F to strike the hoof first, and thence to out onward tothe center of knife; also, by means of the co-operation of knife F andshear-blade z in slightlydifferent plants horizontal to each other thereis virtually effected a double out.

\V hat, therefore, I claim is 1. In a hoof-cutting tool, thecombination, with jaw B, provided with knife F, having a straightcutting-edge, ol'jaw I), provided with shear-blade '1 having a concaveeuttingedge, substantially as set forth.

, 2. In a hoot-trimming tool,the combination, with strai ght-cntting-edg'ed k nife F, located on jaw B, of concave and beveled shear-blockh and conoaved-ed ge shear-blade i, located on'j aw 1), the concavedimensions of said blade and said block substantially rallying with eachother, substantially as set forth.

block, and anvil-block G, located in rear of said blade, substantiallyas set forth.

In testimony that I claim the foregoing to be my invention I havehereunto set my hand this 28th day of January, A. 1"). 1886.
